Processor Numbering
Connection of the ServerNet cables from the LSU to the PICs in p-switch slots 10 through 13
determines the number of the associated logical processor. For more information, see “LSUs to
Processor Switches and Processor IDs” (page 70).
This example of a triplex processor shows the ServerNet cabling to the p-switch PIC in slot 10 that
defines processors 0, 1, 2, and 3. This configuration is only an example to be used for
understanding the interconnection.
